BACKGROUND: Comparisons of peri-operative complications associated with paediatric (≤16 years) and adult anaesthesia are poorly available, especially in which cardiac surgery, organ transplantation and neurosurgery are involved. OBJECTIVE: The aim of this study was to evaluate the nature and incidence of peri-operative complications that might be due to anaesthesia and to identify independent risk factors for complications in children and adults, including those undergoing cardiac surgery, organ transplantation and neurosurgery...

Over many centuries, wounds of the heart were thought to be fatal. With the introduction of first anaesthesia and then antiseptic surgery in the second half of the 19th century, there was an explosion in surgery; the abdominal cavity, the chest, the skull were explored and operated upon and yet the heart was considered to be a 'no go' region of the body. One of the greatest and most innovative surgeons of that time, Theodor Billroth of Vienna, who must be considered one of the fathers of modern surgery, with pioneering work on many parts of the body, wrote: 'The surgeon who attempts to suture a wound of the heart should lose the respect of his colleagues'...

Cardiac anesthesia and critical care provide an important continuum of care for patients with congenital heart disease. Clinicians in both areas work in complex environments in which the interactions between humans and technology is critical. Understanding our contributions to outcomes (modifiable risk) and our ability to perceive and predict an evolving clinical state (low failure-to-predict rate) are important performance metrics. Improved methods for capturing continuous physiologic signals will allow for new and interactive approaches to data visualization, and for sophisticated and iterative data modeling that will help define a patient's phenotype and response to treatment (precision physiology)...

OBJECTIVE: Postoperative cognitive decline (POCD) is known to occur quite frequently after a cardiac surgery, especially in older population. Few studies specifically focused on its incidence and characteristics in gynecological setting. METHODS: Current opinions and future applications of POCD studies in gynecological setting have been discussed. RESULT: There are still many questions and issues about POCD in gynecological setting that remain unanswered as well as numerous research fields that have not been still explored...

Williams-Beuren syndrome is the clinical manifestation of a congenital genetic disorder in the elastin gene, among others. There is a history of cardiac arrest refractory to resuscitation manoeuvres in anaesthesia. The incidence of myocardial ischaemia is high during anaesthetic induction, but there are patients who do not have this condition yet also have had very serious cardiac events, and issues that are still to be resolved. Case descriptions will enable the common pathophysiological factors to be defined, and decrease morbidity and mortality...

BACKGROUND: The ccNexfin system uses the CO-trek algorithm to analyse a non-invasively obtained arterial pressure waveform and calculate cardiac output (NEXCO). It remains matter of debate whether NEXCO can replace invasive, pulmonary artery catheter derived, cold-bolus pulmonary thermodilution cardiac output measurement (PACCO). This study aimed at testing NEXCO-PACCO agreement in a large sample size, multi-centre study. We hypothesized that agreement between NEXCO and PACCO would be demonstrated by a mean accuracy (bias) < 0...

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disease associated with sudden cardiac death (SCD) mainly due to ventricular tachycardia (VT) or fibrillation even though life-threatening bradycardia occurs. Risk stratification takes several variables into consideration including non-sustained VT (NSVT). An implantable cardioverter defibrillator effectively prevents SCD.Atrial fibrillation (AF) is common among patients with HCM and warrants anticoagulation even without conventional risk factors according to European guidelines...

Even though, the incidence of Mitral Stenosis (MS) has reduced grossly, it still remains a health problem in developing countries and is the most common rheumatic valvular lesion encountered in pregnant patients. The already compromised cardiac status of a pregnant female deteriorates further by the presence of MS. So, pregnancy is a common situation during which untreated and frequently poorly tolerated MS are first diagnosed. Percutaneous Balloon Mitral Valvuloplasty (BMV) may be life saving in such a setting and a multidisciplinary approach in the management reduces the mortality and morbidity during the procedure...

Administering anaesthesia for elderly patients with chronic schizophrenia has always been a great challenge to anaesthetists. These patients will usually be on multiple antipsychotic drugs for many years and may lead to delayed awakening, cardiovascular instability, arrhythmias and sudden cardiac death during general anaesthesia. This case report is about the perioperative anaesthetic management of an elderly schizophrenic patient undergoing removal of femur implant. This article will explore important drug interactions and available options for a successful anaesthesia...

BACKGROUND: Propofol is one of the most commonly used intravenous anaesthetic drugs for surgical procedures. The use of propofol for sedation is also common practice during endoscopic procedures, electrophysiology studies, and ablation procedures, as well as pacemaker and defibrillator implantation. It was found that propofol alters the electrophysiologic properties of the heart and its conduction system. The effects of propofol on pacing thresholds are unknown and could have implications for pacemaker (PM) and defibrillator (ICD) implantation procedures, as well as sedation and anaesthesia in PM and ICD patients in general...

BACKGROUND: Cardiac output (CO) is an important haemodynamic parameter to monitor in patients during surgery. However, the majority of the techniques for measuring CO have a limited application in veterinary practice due to their invasive approach and associated complexity and risks. Transoesophageal echocardiography (TEE) is a technique used to monitor cardiac function in human patients during surgical procedures and allows CO to be measured non-invasively. This prospective clinical study aimed to compare the transoesophageal echocardiography using a transgastric view of the left ventricular outflow tract (LVOT) and the thermodilution (TD) technique for the assessment of CO during mean arterial pressure of 65-80 mmHg (normotension) and <65 mmHg (hypotension) in dogs undergoing elective surgery...

Background: We have previously reported that stroke volume is reduced in a majority of elderly patients undergoing surgical repair of hip fracture before and after intrathecal injection of anaesthetic. We aimed to investigate these observations further in a prospective study of elderly patients undergoing elective hip or knee arthroplasty under spinal anaesthesia. Methods: Patients ≥65 yr undergoing elective arthroplasty were monitored with LiDCOplus™ preoperatively (baseline), before and continuously for 45 min after spinal anaesthesia...

Accidental awareness during general anaesthesia can arise from a failure to deliver sufficient anaesthetic agent, or from a patient's resistance to an expected sufficient dose of such an agent. Awareness is 'explicit' if the patient is subsequently able to recall the event. We conducted a systematic review into the effect of nitrous oxide used as part of a general anaesthetic on the risk of accidental awareness in people over the age of five years undergoing general anaesthesia for surgery. We included 15 randomised controlled trials, 14 of which, representing a total of 3439 participants, were included in our primary analysis of the frequency of accidental awareness events...

OBJECTIVE: Neurological dysfunction remains a devastating postoperative complication in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB), and previous studies have shown that inhalation anaesthesia and total intravenous anaesthesia (TIVA) may produce different degrees of cerebral protection in these patients. Therefore, we conducted a systematic literature review and meta-analysis to compare the neuroprotective effects of inhalation anaesthesia and TIVA. DESIGN: Searching in PubMed, EMBASE, Science Direct/Elsevier, China National Knowledge Infrastructure and Cochrane Library up to August 2016, we selected related randomised controlled trials for this meta-analysis...
